Hi @WillusDong, This implementation supports only device designed by ipv4Address.publicAddress and single port.

Try something like this.

{
    "duration": 86400,
    "device": {
        "ipv4Address": {
            "publicAddress": "192.168.0.2"
        }
    },
    "applicationServer": {
        "ipv4Address": "192.168.0.1"
    },
    "devicePorts": {
        "ports": [
            5022
        ]
    },
    "applicationServerPorts": {
        "ports": [
            5010
        ]
    },
    "qosProfile": "vp251iMf1TJiFQq1jpzihd9E9K40.lHI89cTyIdtumWq2VB_cCM4KmUqYvUP8TJCzXab1PvqjaS-vIWwltxHsUjUN",

Hello @patrice-conil,

Thanks for the quick turnaround, when I tried with this payload and the same configuratioin mentioned earlier, I got this errors - 'Default' client configuration is not initialized.
Any thoughts?

Hi @WillusDong, I think you didn't provide values for CLIENT_ID and CLIENT_SECRET in your env and these values are used to configure oidc client. Hope this helps

[WillusDong]

Thanks @patrice-conil,

If provided, with customized values as follows, the same error returns: export CLIENT_ID=appId; export CLIENT_SECRET=secret; java -jar ./build/camara-qod-0.9.0-runner.jar

Hi @WillusDong, I think your scef client config is wrong : https://localhost:8888/http://localhost:8888/apigm should be something like http://localhost:8888/apigm => default client is not initialized.

[WillusDong]

Still getting the same error with suggested change.

Would you provide complete settings that works with wiremock?

Thanks.

[patrice-conil]

Hi @WillusDong, I pushed a new version more user friendly that need no additional config to run and auto-provision redis content. Could you see if it solve your problem?

[WillusDong]

Thanks @patrice-conil Will give it a try and keep you updated.

[WillusDong]

Sorry for the delay, The update makes the deployment much easier, I would just need to make sure that wiremock is listening on port 8888, redis server is listening on localhost:6370, and it works fine.

Thanks.

[patrice-conil]

Hi @WillusDong, You have to download wiremock standalone jar and launch it by hand with something like

java -jar ~/Downloads/wiremock-jre8-standalone-2.35.0.jar --port 8888 --bind-address localhost -vv

from the project's wiremock folder (where __files and mappings reside) Enjoy
